Answer:

197200atm

Explanation:

There are different units to express pressure of a gas, some of them are atmosphere, Bar, Kilopascal, Pascal, torr among other.

In this exercise we need to know the equivalence between atm and Kpa.

                                             if, 1kp=0,00986atm

then,

(2,000 x104kPa)*(0,00986atm)/1Kpa= 0,00986 atm

<u>Answer:</u>

<em>197.4 atm is the Answer.</em>

<em></em>

<u>Explanation:</u>

Pressure can be expressed in unit of torr, mm Hg, psi, atm, kPa etc

<em>1 atm = 760 torr = 760 mm Hg = 14.7 psi = 101.325 kPa </em>

So Here to convert atm to kPa the conversion factor is either \frac {1atm}{101.325kPa} or \frac {101.325kPa}{1atm}

We need the answer in atm so kPa should get cancel and it should be in the denominator

2.000 \times 10^4 kPa\times \frac {1atm}{101.325kPa}

=197.4 atm is the Answer.

A second reaction mixture was made up in the following way:
Leya [2.2K]

A. We can calculate the initial concentrations of each by the formula:

initial concentration ci = initial volume * initial concentration / total mixture volume

where,

total mixture volume = 10 mL + 20 mL + 10 mL + 10 mL = 50 mL

ci (acetone) = 10 mL * 4.0 M / 50 mL = 0.8 M

ci (H+) = 20 mL * 1.0 M / 50 mL = 0.4 M   (note: there is only 1 H+ per 1 HCl)

ci (I2) = 10 mL * 0.0050 M / 50 mL = 0.001 M

 

B. The rate of reaction is determined to be complete when all of I2 is consumed. This is signified by complete disappearance of I2 color in the solution. The rate therefore is:

rate of reaction = 0.001 M / 120 seconds

rate of reaction = 8.33 x 10^-6 M / s

How many moles of hydrogen atoms are in 1 mole of sulfuric acid?
Hunter-Best [27]

one mole of sulfuric acid will contain 2 moles of hydrogen atoms. The molar mass of sulfuric acid is 98.0795 g/mol. This means that every mole of sulfuric acid has a mass of 98.0795 g. Since you're dealing with one mole of sulfuric acid, it follows that you will also be dealing with two moles of hydrogen.
